Mixed Signal/Analog

Linear Technology has today announced the introduction of a DC to 300MHz dual output buffer/driver/logic translator, ideal for converting sine waves into low phase noise logic level signals. Prior solutions were unable to perform this conversion without introducing a significant amount of jitter. The LTC6957 converts any DC to 300MHz reference frequency into dual LVPECL, LVDS or CMOS outputs with exceptionally low additive jitter of 45fsRMS (LVPE...

Touchstone Semiconductor today announced it has added four new, high-accuracy, micropower timer ICs to its rapidly expanding family of “NanoWatt Analog” timer integrated circuits. In addition to all other Touchstone Semiconductor ICs, these new analog timers are all in stock and ready to ship from Digi-Key, Touchstone’s authorized distributor.

Touchstone Semiconductor today announced the immediate availability of the TS7001, its newest 12-bit 187.5-ksps analog-to-digital converter (ADC) that can be used as a 1.5x faster/50% lower INL drop-in upgrade to the Analog Devices AD7887A. The TS7001 is a 50% smaller footprint and is also 1.5x faster versus the high-grade AD7887B in an SOIC-8.

Analog Devices introduced today a high performance MEMS microphone developed specifically for hearing aid applications. When compared to legacy solutions like electret condenser microphones, the ADMP801 is not only smaller in size at only 7.3 cubic millimeters, but also offers greater performance stability over time, temperature, and environmental changes, produces very low equivalent input noise at 27 dBA SPL, and consumes only 17 µA at 1Vsuppl...

The FN5040HV sine wave filters from the market leader Schaffner are now available for 690VAC and 600VAC applications. In combination with variable speed drives extra losses in AC motors are reduced and help to prolongate the motor life time.

The seemingly insatiable demand for ever-thinner profiles is compromising the audio quality output of even top-end flat panel TVs, thereby creating enormous market opportunities for digital sound projectors (SoundBars) capable of delivering an audio fidelity that matches today’s high-definition video reproduction.

Fujitsu has enabled the large-scale deployment of single-wavelength 100Gbps optical transport systems worldwide. Fujitsu's expertise in mixed-signal, thermal, power-optimisation and high-performance package design are key ingredients for providing SoC ASIC solutions to system vendors, paving the way for the necessary upgrade to global networking infrastructure brought on by ever-increasing bandwidth demand and traffic flow.

Linear Technology Corporation introduces the LTC2314-14, a 14-bit 4.5Msps successive approximation register (SAR) ADC in a tiny 8-lead TSOT-23 package, offering up to 90% reduction in size over competing solutions for space-conscious applications.

Conexant Systems today announced the CX3000, its new high-performance, ultra low-power, Class H headphone amplifier with I2C control. CX3000 is the first Class-H amplifier to drive up to 2.8V into matching high impedance headphones with 106dB SNR and 100+ dB THD.

In a push for better sound quality and more output volume, leading mobile phone makers have been raising the internal voltage used to drive micro speakers – from 3.3V through to 5V, and recently as high as 8V. NXP is launching its new TFA9890 speaker driver IC, which enables an unprecedented 9.5V boost voltage from an integrated DC-DC converter. Increasing the voltage headroom in the audio driver IC prevents amplifier clipping and keeps sound q...
